Capgo fails to clean up channel permission overrides when a user's last organization role binding is deleted, leaving stale overrides active. Attackers can retain channel-specific permissions after their base RBAC access has been revoked to perform unauthorized actions like changing production OT...

CVE-2026-88860 Capgo Authorization Bypass via Stale Channel Permission Overrides

Capgo fails to clean up channel permission overrides when a user's last organization role binding is deleted, leaving stale overrides active. Attackers can retain channel-specific permissions after their base RBAC access has been revoked to perform unauthorized actions like changing production OT...

CVE-2026-88860

Capgo , an OTA update platform, is affected by an authorization bypass caused by stale channel permission overrides. When a user's last organization role binding is deleted, Capgo fails to clean up associated channel-level permission overrides, leaving them active. An attacker with a previously r...

GhostESP v2.1.2-pre2

The ESP-IDF-native wireless security platform for ESP32. Deep Wi-Fi and BLE assessment, research-grade capture and export, and a real app ecosystem. Built directly on Espressif's ESP-IDF rather than through the Arduino core, so new silicon and radio features land first and there is no abstraction...

CVE-2026-11811 Socket file-descriptor leak in UpdateHub OTA client start_coap_client() leading to resource-exhaustion DoS

The UpdateHub over-the-air update client's startcoapclient in subsys/mgmt/updatehub/updatehub.c leaks the CoAP/DTLS socket descriptor on its connection-setup failure paths. The shared error: cleanup gated socket closing on a ret 0 flag, but ret was set to -1 immediately after the socket was...

CVE-2026-11811

The CVE-2026-11811 entry documents a socket-file-descriptor leak in the UpdateHub OTA client (start_coap_client) when connection-setup fails. The leak occurs because on failure paths the cleanup gate does not call cleanup_connection(), leaving an open descriptor in the global ctx.sock that is ove...

CVE-2026-11810

The UpdateHub firmware-update agent's probe handler zimplupdatehubprobe in subsys/mgmt/updatehub/updatehub.c parses the JSON metadata returned by the update server into a fixed two-level nested-array struct. After parsing it validates only the outer array length objectslen != 2 and then...

CVE-2026-11809

The UpdateHub OTA client in subsys/mgmt/updatehub/updatehub.c contains an out-of-bounds / uninitialized-memory read in zimplupdatehubprobe. The probe response from the UpdateHub server is copied into a heap buffer metadata that is correctly NUL-terminated, but a second buffer metadatacopy is...

CVE-2026-11809 UpdateHub probe: uninitialized-heap out-of-bounds read of network-supplied metadata

The UpdateHub OTA client in subsys/mgmt/updatehub/updatehub.c contains an out-of-bounds / uninitialized-memory read in zimplupdatehubprobe. The probe response from the UpdateHub server is copied into a heap buffer metadata that is correctly NUL-terminated, but a second buffer metadatacopy is...

CVE-2026-11809

CVE-2026-11809 (Zephyr UpdateHub OTA client) : The UpdateHub probe in subsys/mgmt/updatehub/updatehub.c uses a second heap buffer (metadata_copy) via memcpy(metadata_copy, metadata, strlen(metadata)) without zeroing. This omits the terminating NUL, so a subsequent json_obj_parse(metadata_copy, st...
